This report focuses on improving the air performance and air quality of the Bombardier Global 7500. A test rig is designed and built, with the intentions of simulating the inlet ducting of the Global 7500. The performance of the test rig has been measured, and the ducting is prepared for testing. Preparations have been made to test the effect that various air outlets have on the performance of the ducting. The temperature can vary throughout the cabin, causing discomfort for passengers, it is possible that the inlet ducting is responsible for this. Additionally, the effect of numerous air pollutants has been explored and a focus has been made to test particulate matter and carbon monoxide. The Honeywell HPM Series and the Adafruit MiCS5524 have been suggested for detecting particulate matter and carbon monoxide respectively. The ducting designed can be used for various air performance and air quality research in the future.
